Rapid Loss of Sunlight Could Have Unleashed Snowball Earth Events in The Past – ScienceAlert

Not all ice ages are equally brutal. In the most extreme glaciation events known to science, ice stretches out from Earth’s polar regions and extends all the way into lower latitudes, literally reshaping the face of the planet.
Evidence for such epic transitions can be found in the geologic record, most recently in formidable glaciations during the Cryogenian period. Scientists think these extreme cooling events had potentially global reach and ramifications: a phenomenon called ‘Snowball Earth…
